Allega un dmesg

Dove hai il cdrom? (canale, master o slave...)

Potrebbe essere hdb? (primary slave?)

[texerasmo]

credo di si a questo punto.
dovrei smontare il pc?

[ilsensine]

Prova a caricare i moduli
ide-cd
cdrom
e ricattura il dmesg

[texerasmo]

brutta notizia
[root@localhost ~]# modprobe -l |grep cdrom
[root@localhost ~]# modprobe -l |grep ide-cd
il risultato per entrambi è negativo
non ho questi moduli.
Dovrei ricompilare il kernel?
Questa è un macchina dove ho i servizi di rete

[B3nd3r]

Ma avevi in precedenza ricompilato il kernel? Per caso usi settaggi particolari di udev? Oppure usi un nuovo udev con kernel poco recenti?

[ilsensine]

brutta notizia
[root@localhost ~]# modprobe -l |grep cdrom
[root@localhost ~]# modprobe -l |grep ide-cd

Non li hai oppure solo compilati staticamente nel kernel. Mi sembra strano.
Se sono compilati staticamente, ne devi trovare traccia in /proc/kallsyms, se è stato abilitato sul tuo kernel (ad es. con cat /proc/kallsyms |grep ide_cdrom ) ma ad occhio direi che non ci sono proprio.

Compilato builtin. Scelta discutibile, ma non dovrebbe far male...

Non ho idea a questo punto dove sia il problema. Controlla innanzitutto che il cdrom sia effettivamente sul primary slave, che è l'unico che linux rileva (non serve aprire il computer, te lo dice il bios).

Verifica anche che il cdrom non sia per caso "morto" (parti con un livecd per prova).

Se il cdrom funziona, puoi fare solo due cose: compilarti un kernel più recente (con relativa installazione di udev aggiornato e i rischi del caso), oppure, essendo una Redhat ES, contattare la loro assistenza (ne dovreste avere diritto se avete comprato il package).

[texerasmo]

Beccato,
Il cd rom non viene riconosciuto nel bios.

[ilsensine]

Allora cdrom kaputt...
